SPRING-SEAT.

Specification of Letters Patent.

Patented July 4., 1916.

Application filed Julyfi, 1913. Serial No. 777,561.

To all whom itmay concern Be it known that I, OSCAR A. YOUNGREN, acitizen of the United States, residing at Sheridan, Sheridan county, andState of Wyoming, have invented and discovered certain new and usefulImprovements in Spring-Seats, of which the following is a specification.

My said invention consists in an improved construction and arrangementof parts of spring seats especially designed for the use of engineersand firemen in'cabs and locomotives, but also adapted for use in manyother places, whereby such a seat is provided which issupported fromthewall of the cab, or any side support, and occupies a minimum of spaceand may be easily and quickly put into place andsupported in operativeposition or dropped out of, the way as desired, all as will behereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar reference characters indicate similar parts,

Figure 1 is a side elevation of a seat of the character described,embodying my said invention, Fig. 2 a view as seen when looking in thedirection indicated by the arrows from the dotted line 2-'2 in Fig. 1,and Fig. 3 a detail section on the dotted line 33 in Fig. 2.

In said drawings the portions marked A represent a supporting or baseplate, B the main supporting bracket'or bar for the seat, C a housingfor the springs, D the seat'and E a distance rod or brace. A is ofappropriate form and preferably of metal and adapted to be secured bybolts or screws to the side wall of the cab, or any other side supportprovided. Near its lower end it is provided with forwardly projectingarms 10, and with a centrally disposed eye 11, and near its upper end'itis provided with a hook-shaped coupling member 12.

The arm B is of the form best shown in Fig. 1, having at its rear end anupwardly projecting arm having a hook-shaped coupling member 13 adaptedto engage with the hook-shaped coupling member 12 on the base plate A.Adjacent to the angle between the main portion of said bar B and theupwardly extending rear end are downwardly extending arms 14 which fitwithin thesidesof thehousing C. Saidarn B ex- The base plate tendsoutwardly a'distan ce desired for the purpose and supports the seat onits outer end, as will be presently described.

The housing 0 is composed of slotted sides and end cast as a singlepiece or of any other appropriate form to support the spring mechanismand is supported at its rear end between the arms 10 of the base plate Aby means of pivot bolts 15 extending through diagonal slots 16 in saidarms lnto perforations in said housing. The upper side of said housingsupports thearm B which rests and is adapted to have a sliding movementthereon. Said housing C is formed with long slots 17 in its oppositesides'near its rear end and with like slots 18 in its opposite sidesnear its forward end. A cross-bar 19 is mounted to slide in the slots 17and a similar cross-bar 20 is mounted to slide in the slots 18. Saidcross-bars 19 and 20 are connected to each other bya series of stificoiled springs 21, 22, 23, and 2 1, the opposite ends of said springsbeing connected to said oppositely disposed bars. The lower ends of arms14 of the bar B are formed with apertures through which the crossbar 19extends forming a loose connection. Bolts 25 with hook-shaped rear ends26 are hooked around the cross-bar 20 and project through the front endof casing C where they are provided with nuts 26 by which means said bar20 may be adjusted to regulate the tension of the springs connectedtherewith.

The seat bar D is angular having a cushion (Z mounted on the upper sideof its horizontal arm and at its angle is connected by a pivot rod 27 tothe outer end of the bar B. Its vertical arm extends downwardly for adistance below the outer end of said bar B and is connected by a pivot28 to the outer end of the distance rod E. Said distance rod E extendsrearwardly and at its rear end is connected by a pivot-bolt 29 with theeye 11 on the lower end .ofbase plate A.

In operation the parts being in the position shown by whole lines inFig. 1, and the weight of the person being added thereto,

the seat will be depressed as indicated by dotted lines in the samefigure, but the distance rod E cooperating with the supporting bar Bwill serve to maintain the seat D in a horizontal position at allelevations. When it is desired to drop the seat out of use the front endmay be rai ed wh nthebolts 15 the entire structure may be dropped down--ward in a vertical position turning on the pivots 15, and the seat Dwill be held'in its normal relative position to the other parts by meansof the distance rod E'and the bar B. Whenever it is desired to use the.seat itvis only necessary to lift it up into horizontal position, catchthe hook part 13 over the hook part 12 and-it is immediately ready foruse. By adjusting the bolts 25 the tension of the springs may beregulated to adapt the seat for the weight of any user so as to insurethe most comfortable and desirable results.

Having thus fully described my said invention what I claim as new, anddesire to secure by Letters Patent is:

1. A spring seat comprising a supporting plate, a housing pivoted tosaid supporting plate, a seat supporting bar slidingly connected withsaid housingfand provided with a connection by which it may be coupledto and turn on said supportingplate at a' point removedfrom the pivot ofthe housing, springs connected at one end to said seat supporting barand at the other end tosaid housing for supporting said bar yieldingly,and a-seat supported on said bar, substantially as set forth.

2. A spring seat comprising a base having a support, a housing pivotedto said base at a point rearward from said support, a bar slidablymounted on said housing and provided with a part extending in onedirection and formed to engage and turn on the support on said base andwith arms eXtend ing in the opposite direction, springs connected at oneend to said arms and at the other end to said housing, and a seatmounted on the outer end of said bar, substantially as set forth.

3. A spring seat comprising a base having a support, a housing pivotallymounted on said base at a point removed from said support to have alimited sliding movement,

a seat supporting bar mounted on said housing to have a slidingmovement, one end of said seat supporting bar being adapted forconnection with the support on said base, a seat mounted on the outerend of said seat supporting bar, springs connected with said seatsupporting bar at one end and with said housing at the other end, andmeans connected with the base and the seat supporting bar formaintaining said seat in a horizontal position when in use,substantially as set forth.
